Title: Server systems having segregated power circuits for high availability applications

Abstract: According to one embodiment, a server system includes a motherboard partition that includes a motherboard and at least one processor coupled to the motherboard, with each processor being coupled to a memory. The server system also includes a storage partition that includes the memory, and a power circuit being capable of supplying current to the motherboard partition and the storage partition independently, the power circuit including at least two redundant power supplies in parallel in the power circuit, with each redundant power supply being capable of providing an amount of current necessary to operate the server system, and the motherboard partition is adapted to run a server OS. In another embodiment, an active cluster system may include two server systems, with the motherboard partition from each server system being capable of communicating with the other server system's storage partition even if power is removed from the other system's motherboard partition.
